I'm a new RV-9A builder who is currently working on construction of the VS. I have reached the point up to where I need to countersink the lower portion of the rear spar doubler and I am now confused. The plans show as follows:
The problem I have run into is that the AN-426AD4-6 rivet does not fit the corresponding hole either before or after the countersink. Per the plans I have previously match-drilled these holes with a #30 bit. What am I missing here?

I apologize in advance for the elementary question. Any advice would be helpful.
Thanks,
Ethan
